The SN65LVDS391PW is an interface, drivers, receivers and transceivers that utilize the capabilities of low voltage differential signaling, referred to as LVDS. It consists of an input receiver, a differential line driver and a differential line receiver, allowing for the transmission and reception of data across the differential signals. This device typically operates at a range of 25 megabits per second and is commonly used in digital signal processes, in applications such as video displays, HDTVs, and digital signal processors such as FPGAs.

Application Field

The SN65LVDS391PW is a popular device in displays with high input bandwidth and long signal transfer distances. This device is particularly well-suited for operating in industrial and computing applications, due to its improved system stability, low power requirements and higher signal noise margins.

The SN65LVDS391PW is an ideal choice for industrial and older computing applications, providing superior signal strength and fast serial data transfer rates. The low power requirements of the SN65LVDS391PW make it suitable for battery-powered or portable applications, or any applications where power efficiency and reliability are priority. It can also be used in the automotive industry, for automotive displays, lighting, control systems and more.

Working Principle

The SN65LVDS391PW utilizes low voltage differential signaling, which refers to the transmission of signals through two complementary differential signals. The two signals, V+ and V−, are transmitted in opposite directions and amplitudes, allowing for efficient data transfer with many signals combined. Signals transmitted from the SN65LVDS391PW can travel at speeds of up to 25 megabits per second. The SN65LVDS391PW is also related to standard LVDS signaling, which uses two signals transmitted at slightly different amplitudes and phase shift. This allows for the transmitter to adjust data signals according to the differences between the transmitting and receiving amplitudes.

The SN65LVDS391PW utilizes clock data recovery (CDR) systems to detect the differences between the transmitting and receiving signals, and use those differences to adjust the transmitted data signals accordingly. CDR systems operate by aligning the transmitted and received data signals, allowing for improved signal strength and minimize signal noise and interference. Once the data is aligned, it is then transmitted to the receiver via the transmitter’s LVDS interface.

In addition, the SN65LVDS391PW also utilizes phase shifters to adjust the output signals according to the input signals. This ensures that the output transmitted signals are correctly aligned with the receiver’s input data. The phase shifters also ensure that the transmitted signals are not distorted or corrupted while they are in transfer.

The SN65LVDS391PW is an excellent choice for sending data at higher speeds and over long distances. It provides superior signal strength, reliable serial data transfer, and low power requirements making it suitable for battery-powered and portable applications. This device is ideal for industrial, automotive and computing applications.
